Since the film's been rebranded Star Wars: A New Hope, Hamill's been playing the character for over 40 years with The Last Jedi being the latest entry of the franchise slated for a December release. The behind-the-scenes image of a young Hamill cracking his knuckles has been circulating for while, but the actor offered some new perspective on it: It could be the first photo of Luke Skywalker.

The photo, which shows Mark on set in the Tunisian desert, was taken on the first day of filming on March 22 1976. Some fans are convinced that she is Luke Skywalker's daughter however, some believe Skywalker may be is related to Rey in a different way. Does that photo of Hamill look like a man enjoying his first day?
